Alpha: Captain of the Football team, generally chooses one woman, and makes her the Alpha Female
Beta: the next-best-males, respected and valued, loyal to the Alpha. They also choose one woman, which the Alpha doesn’t try and steal.
Gamma: the low-ranked males – neckbeards and WoW nerds.
Omega: the sexual deviant, the stereotypical travelling salesman who seduces the Farmer’s Daughter with promises of love, and then takes off when she gets pregnant. Whether acting out childhood trauma, or simply from a sociopathic nature, the Omega is despised by proper society; unlike the Alpha and Beta he holds no societal respect or power and must attain his status through deviousness and criminality.

The modern problem? Aside from women being out of control, we’ve also managed to brainwash the Alphas and Betas into being cuckolds. The few of us who Get It are forced to pursue an Omega-style route, even if – unlike the criminal scum – we’d prefer to be loyal to a single woman.

I think it’s all down to your internal sense of confidence. After having been around a bit, fallen down a few holes, had some failures and successes, you are a pretty good judge of your chances in general. Others perceive your internal assessment and react to it; your status depends on their knowledge of you. Women find confidence attractive,so sexual success is one of the possible consequences; but it isn’t necessary as a defining marker.
